House Rules Carolyn Burns-McCrave didn't find Mitcham auction buyer

The renovated outer Melbourne home of Channel 7 House Rules design expert Carolyn Burns-McCrave failed to sell at weekend auction.

The four-bedroom Mitchum property passed in on a $1.72 million vendor bid with a $1,795,000 asking price revealed post-auction.

The home, with Hamptons-inspired grey weatherboard exterior, came with initial price hopes of $1.7 to $1.87 million.

The single storey home had been her abode since paying $381,000 in 2003 with her building designer husband, Leonard McCrave.

"Every aspect of this home's design has been well considered and completed to exacting standards," the Noel Jones marketing said.

"Your designer home awaits; embrace this rare opportunity now, and prepare to be wowed."
